Someone set two small fires at the "Mrs. Doubtfire" home in San Francisco, made famous by the film starring Robin Williams, and police are investigating a former patient of the homeowner as a possible suspect. Stephanie Chuang reports.

Police were investigating whether the home was targeted because of what current owner Dr. Douglas K. Ousterhout, a plastic surgeon who works on transgender patients, does for a living.

Ousterhout told police investigators that a former patient of his could be behind the fires, making that person a likely suspect. Esparza said police is not discussing the relationship between the suspect and the victim at this time.
